1. First of all, we compare the product materials. The aluminum alloy has a low specific gravity and the same product shape. The cost of the aluminum alloy material is low.

2. Compared with the cost of the mold, the aluminum alloy has a high temperature, the mold life is short, the feed port is large, and the mold is large, so that the mold cost is high.

3. From the comparison of processing cost, zinc alloy is easy to form, some complex structures can be directly exported, and aluminum alloy has poor fluidity, so there are many machining operations involved at the back, and all aluminum alloys have high cost.

4. From the appearance of the comparison, if your product surface is polished and required high quality appearance, then you have to use zinc alloy. The aluminum alloy material is difficult to achieve high surface quality requirements, because the aluminum alloy die-casting performance is poor, and the pores of the product are easy to be printed on the surface of the product, and the surface quality is poor after electroplating.

5. From the top of the weight, the aluminum alloy is only 2.5 times that of the zinc alloy, and the aluminum alloy is lighter.

6. Aluminum alloy has good strength and corrosion resistance.

Whether the zinc alloy or aluminum alloy is used by the purchaser depends on the use of the product and the effect that needs to be achieved. Zinc alloy and aluminum alloy have their unique advantages and disadvantages.
